UNITED STATES PATENT OFFICE 1 Claim.

'Ihis invention relates to mechanical means, the general object of the invention being to provide means whereby one driven member may be driven in one direction and another in the oppo- Site direction at the same speed, the device being used to turn logs on a saw mill carriage.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim. Y

In describing my invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views and in Figure 1 is an elevation of the invention.

Figure 2 is a section on line 2-2 of Figure 1,

showing how the hooks come in contact with the log.

Figure 3 is a side view of the planetary gearing.

In the drawing the numeral I indicates a shaft which has its ends journaled in the beams I0.

A pinion 2 is keyed to shaft I, and the planetary gearing, Fig. 3, is rotatably mounted on shaft I. Another pinion 3 is also rotatably mounted on shaft I and it meshes with planetary gearing 4 which meshes with pinion 2. Pinions 2 and 3 are the same size. Beams (or arms) 5 and 6 are rotatably mounted on shaft I. Sprocket 'I is rotatably mounted on shaft I and is fastened to the back of pinion 3. Another sprocket 8 is mounted as an idler at the top of the beams 5 and 6 in line with sprocket 'I. On shaft I a thrust collar I3 is fastened against the hub of sprocket 1 to hold the gearing in mesh and the planetary gearing is fastened to shim I9 which is bolted toI beams 5 andi 6 by bolts II. Chain 9 runs on sprockets 'I and 8, between which sprockets 'I and 8 on the log side of shim I9 is fastened an iron track which holds chain 9 and hooks I5 rmly against the log; hooks I5 being fastened to attachment links I6 by bolts I'I. Sprocket 8 rotates on shaft 2I, and braking device 20 rests on the hub of sprocket 8 to produce necessary friction to lift beams 5 and 6 from a horizontal position to a vertical position when shaft I is turned toward the log; also when the shaft I is turned in a reverse direction it is caused to return to a horizontal position so that logs may be rolled over it to the carriage. When shaft I rotates toward the log it lifts beams 5 and 6 with the chain 9 and hooks I5 against the log 23; it then stops and as pinion 2 continues to rotate, planetary gears 22 rotate on shaft 4 meshing with pinion 3 which then rotates in a reverse direction 5 carrying with it the chain and hooks. The hooks catch in the log and turn it toward the carriage. Pinions 22 are held in place by nuts I4 on shaft 4. When power is applied (by power transmission means patented by me under Patent ,#1,691,- 10 834) to gear I2 it makes a very satisfactory combination.

It is to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided, that 15 such changes fall within the scope of the appended claim.

What I claim isf- A log turner comprising a shaft, means for rotatably supporting the shaft, a pinion keyed 20 to the shaft, a second pinion, like the rst, with a sprocket wheel fastened to it, rotatably mlounted on the shaft, planetary gearingV rotatably mounted on a cross-shaft and meshing with the two pinions, the planetary gearing being fastened 25 to two beams which are rotatably mounted on the shaft one on one side of the two pinions and the other on the other side, a second sprocket wheel mounted as an idler at the other end of the beams in line with the rst sprocket wheel, an 30 endless chain with hooks attached to it running on the two sprocket wheels, a track supported by the two beams between the two sprocket wheels on the front side so as to force the hooks firmly against the 10g, a brake on the idler sprocket 35 wheel to furnish enough friction to lift the beams when the shaft is turned toward the log, whereby when the chain strikes the log the beams stop and as the shaft turns on, carrying with it the pinion keyed to it and as the planetary gearing 40 that is secured to the beams that support the idler sprocket wheel and chain also stop then the rotatably mounted pinion and sprocket wheel f turn in an opposite direction carrying the chain with its hooks up against the log forcing it to 45 turn; power being applied to the shaft by a spur gear and pinion connected to power transmission means; the beams with the idler sprocket wheel returns to a horizontal position when the shaft is turned in a reverse direction so that logs may 50 be rolled over it to the carriage. f
